Application filed catcher 13, 1915. Serial No. 55,603.

To all whom it may comm.-

Be it known'that I, Jaime 'l. Rosana,

citizen of the United States, residing at Seattle, in the county of King and State Washingt0n,have invented a certain new and useful Improvement in VVheel-Rims, of which the'following is a specification.

My invention relates to improvements in metal Wheel-rimsWhich are adapted to be removably mounted upon the spoke-sup ported fellies of wheels of vehicles as of wheels of automobiles, and upon which wheelrims may be removahly mounted pneumatic tires of a common form, and the object of my invention is to provide a, wheel-rim upon which may be removably mounted, quickly and easily, a pneumatic, tire and which wheel-rim, itself, may be readily and re movably mounted upon the spoke-supported folly of a wheel, whereby, when it hecomes necessary to remove a tire to repair it or to replace it with a new one, then such all) ' securely moun Wheel-rini may he quickly and easily removed fromits position on the telly die Wheel and the pneumatic tire then readily removed from said whcel-rim, whereupon such pneumatic tire, after being repaired, or a new tire of like form, may be quickly and properly disposed and fastened on said wheel-rim and said wheel-rim then replaced and fastened on the felly of said wheel. fl accomplish this object by devices illustrated in the accompanying drawings wherein- Figure 1 is a vi cw in front elevation of an automobile wheel upon which is mounted a Wheel-rim en'ibodying my invention together with a pneumatic tire mounted on said wheel-rim; Fig. 2 is an enlarged view of the same in radial section on line a", w of Fig. 1, the hub portion of said wheel being broken away; Fig. 3 is an enlarged view in radial section on broken line 3 12 of Fig. 1, showing details of my invention; and Fig. l: is an enlarged view in radial section of a portion of a wheel-rim embodying my invention showing a modified form of details thereof.

Referring to the drawings, throughout which like reference numerals indicate like parts, 5 designates the hubofa wheel from which hub 5 extends radially a plurality of spokes 6 upon the outer ends of which is ted a concentrically disposed felly portion 7.

Upon the rear side surface of the folly portion 7,111 a position concentric therewith,

is fastened an annular flange 8 of a larger external diameter than the diameter ofthe periphery of the telly portion 7, the position of which annular flange 8 and its cross-sectional'shape is clearly indicated in Fig. 2.

Disposedto encircle the telly portion 7 is a metal wheel-rim comprising twoseparable hands 9 and 10 which are provided each with an integral flange on its outer edge portion, as flanges 11' and 12 respectively, and Whose inner edge portions are joined by a separable telescopic joint, as shown in Fig. 2, thus to form a channeled band around said telly portion 7, one side portion of which channel band engages with and is supported by the annular flange 8, while the other side portion thereof engages with and is sup ported by a plurality of clamps 13 whichare fastened to the'front side surface of the telly portion 7 at equidistant circumferential points thereof by means of bolts 14, the cross-sectional shape and the position of each of said clamps 12-3 with respect to the band 10, the flange 12 and the telly portion '7 being more clearly illustrated in Fig. 3.

when the two scg iarable hands 9 and 10 of the wheel-rim are thus disposed-and fas toned on the telly portion 7 the flanges ll. and 12 of said bands 9 and 10 respec rely, serve to maintainthe telescopic j tween said bandst) and 10; and the int of such telescopic joint is further by means of locking bars 15 one end or each of which is pivotally hinged to a different pair of integrally connected lugs which are inlaid within the front side ed ge the band 10 and the flange 12 thereof, said pairs of lugs 16 being disposed at equi-dista points and there fastened by screws 17, each of said locking bars 1'5 being disposed to extend from its lugs 16 directly across the band 10 to lie between and project beyond. two lugs which are integral with the band the wheel-rim upon which is mounted a.

pneumatic tire, of a io-rm'well known, the outer casing 19 of which only is shown.

A portion of the'peripheral surface of the band 10 is covered with-a strip 20 of canvas or other 'sott material whereby the .inner elastic air tube (not shown) maybe protected from direct contact with the metal surface of said band 10 when such air tube is inflated in its normal position within said outer casing 19. r

The band 10 is provided with a slot 21 which extends from its inner edge past the telescopic joint and beyond the center of the distance between the flanges 11 and 12 to.

form an opening through which" may extend a nipple 22 that connects with the inner elastic air tube, not shown.

In order to remove this Wheel-rim from the felly portion 7 the bolts 14: are unscrewed. for a sufficient distance to permit the clamps 13 to disengage from the band 10 andthe flange 12 thereof, whereupon such clamps 13 may turn on'the bolts 14 to a position that will permit the wheel-rim freelyto be withdrawn from the felly portion 7 and then to remove the pneumatic tire from said wheel-rim the locking bars 15 are swung on their. pivots to disengage their outer-ends from the lugs 18 whereupon'the' band 9 will readily separate from the band 10, at the telescopic joint that unites them,

- with the result that the outer casing 19 of the tire, with its inclosed elastic'inner tube, will be released to permit it readily to be removed from the band 10.

When. a pneumatic-tire on the wheQLrim, the bands 9 and 10 .being separated, the outer casing 19 with its inner tube'inclosed therein is placed on the band 10, the nipple 22 being disposed i-n'the slot 21, and thereupon, the band 9 is telescopi- 'cally joined to the band 10, and the locking bars 15 swung into their positions between the respective ones of the lugs 18 securely to lock said bands 9 and .10 together; and to retain said locking ban-s15 in their positions while the wheel-rim is not mounted on the felly portion 7, 1 have provided for each of said locking b'ars 15 a pivoted button 23, as v shown in Fig. 2, pivotally secured to one of the lugs 18, which button 23 is of thin sheet metal and which may swing into a position crosswise ofthe locking bar 15 to retain such bar 15 in its locked position between a pair of said lugs 18 in an obvious manner. When a pneumatic tire is thus mounted on the wheel-rim the wheel-rim -may be mounted securely on the folly portion 7 by placing the I hand 9.and its flange 11 in engagement with ,thei flange 8 -.nd thereupon the clamps 13 'maybe turned into a position which will cause their engagement with the band 10 and its flange 12, after which the bolts 14 are turnedtightly to force the clamps 13 against the band 10. and its flange 12, to clamp the band 9 and its flange 11 against the flange .8

that is fastened to the rear side surface of the felly portion7, thus to secure the wheel-rim on the telly portion 7 in an obvious manner.

It will be observed that when the outer casing is disposed inits normal position of operation between the flanges 11 and 12 of the wheel-rim, then a portion'of one edge of the outer casing 19 will cover the telescopic joint between the bands 9 and 10, thus to prevent any water or moisture from gaining access tn the interior of said casing 19 through said telescopic joint.

In Fig. 4c 1 have shown a modified form, of lug, as lug 24;, which corresponds in function to each of the integrally united lugs 16 of Figs. 1 and 2, which lug 24; is not inlaid sionsand arrangement of parts of my inven- 'tion without departing from the spirit thereof.

1 v What I claim is: is to be replaced A wheel rim of the class described which embodies two flanged bands united by atelescopic-"joint; a plurality of pairs of lugs disposed to project inwardly from the internal side of one of said flanged hands; a plurality of locking bars, each having one of its ends hinged to the other one" ofsaid' flanged bands and each having its free end portion of greater width to 'form' oppositely dis posed integral locking lugs, said locking bars being disposed each to adapt it to be swingingly moved toengage one of its opposite side surfaces with the internal surfaces of both of said flanged bands and to make a locking engagement between its said looking lugs and one of said pairs of lugs, where by the other, of its opposite side surf-aces shall be disposed to adapt, said locking bar to engage with and rest upon the periphery of a wheel to support said two flanged bands in a concentric ppsition thereon; and a button pivotally associated with one of-the lugs of each pair of lugs and adapted to be turned to a position to maintain the adjacent locking bar in its locked position. v I In; witness whereof, Ihereunto subscribe my name this second day of October, A. D.
